Nexperia Bus Transceiver 18-Bit Non-Inverting TTL Surface Mount, 20-Pin SOT-8020 74LVC245ABZX

Nexperia 74LVC245ABZX is an 18-bit non-inverting bus transceiver designed for seamless data transfer across digital bus systems. It integrates 18 bidirectional CMOS channels with non-inverting TTL logic levels, allowing for mixed 3.3 V and 5 V device interfacing in industrial, communication, and embedded system applications.

This bus transceiver features an output enable (OE) pin that places outputs into a high-impedance OFF-state when asserted, and a direction control (DIR) pin to select the data direction. The device includes Schmitt-trigger inputs that tolerate slow input signal transitions, enhancing noise immunity in demanding environments.

With a supply voltage range from 1.2 V up to 3.6 V, this device fits low-voltage systems while maintaining robustness. Partial power-down mode via IOFF circuitry prevents damaging bus backflow when powered down. The 20-pin SOT-8020 surface mount package measures 2 mm in length and 480 μm in height, allowing compact PCB layouts.

Wide voltage supply range from 1.2 V to 3.6 V for versatile system integration. 3-state outputs and bus hold feature ensure reliable data communication. TTL compatible inputs and outputs facilitate interfacing with legacy and modern logic.

Operating temperature from -40°C to 125°C for harsh industrial environments. Compact 20-pin surface mount for space-efficient design. RoHS compliant ensuring environmental safety and regulation adherence. Low propagation delay time of 4.1 ns enables high-speed data transfer.

Schmitt-trigger inputs enhance noise immunity and signal integrity. IOFF circuitry supports partial power-down mode preventing backflow currents. Direction control and output enable pins provide flexible bus control options.

This bus transceiver suits electronics manufacturers, embedded systems design, communications equipment, industrial automation, and other applications requiring robust logic level bus communication. Nexperia's high-quality semiconductor components ensure reliable system performance and compliance with modern safety standards.
